RV generators are meant to provide comfort. Gas generators, especially, are well-suited for long-lasting performances. The question is raised when you’ve to figure out the optimal running performance of an RV generator in a full tank of gas.

If you’re going to a campsite far from a gas station, it is best to fill up the tank to avoid further checking. A full tank of gas will have support in this regard. Now, you’ll have to consider several factors to know the duration of running an RV generator on a full gas tank.

RV Generator Run On a Full Tank of Gas

a) Tank capacity: A gas tank can range from 1 gallon to 10 gallons. Which one is yours? As we discussed earlier, a well-maintained Onan 4000 generator will need 0.5 gallons of fuel per hour. Thereby, 1 gallon will give you a total of 2 hours of support. The more you increase the tank capacity, the better support you’ll get based on the tank capacity.

b) Wattage: When you’re sure about the tank capacity, the next thing you’ll need is the wattage. RV generators are available in two configurations: built-in and portable. The wattage varies in accordance with this. A built-in RV generator usage varies within 8-13 hours on a full gas tank. A portable gas generator will run based on its wattage and the requirement of your RV.

For instance, if you’re boondocking, a portable gas generator will have to support you for at least 8 hours. Suppose the required wattage at your RV is 3000 wattage. Now, you’ll need a generator that has the capability of providing 8 hours of support of 3000 watts on a full tank. The larger the wattage is, the larger the tank should be. This is how the wattage will determine the RV generator’s duration.

c) Frequency: Another important factor in determining the duration is your usage frequency. If you’re looking for non-stop support for more than 6 hours, a gas tank above 5 gallons will be the ideal solution. The small tank will have long support through the RV generator for infrequent usage.

d) Weather: You must not neglect the weather when devising a plan to use the gas RV generator. The power from a full tank of gas differs according to the weather. In cold weather, the generator has to support for non-stop 8-13 hours. The tank size, as well as wattage, should be maximum. The same happens while running the AC system of your RV.

But, in neutral weather, the support will be highly optimized. You’ll get a longer duration from the full tank of gas.

e) Ventilation and interior of RV: The last but not the least important factor is the RV’s ventilation and interior space. A spacious RV-like motorhome is surely in need of higher support. The running duration will be lessened proportionately. On the other hand, the duration will be more if you have a slightly less spacious RV.

The basics are power production and power usage from an RV generator with a full gas tank. You need to optimize according to the RV generator and its ability to support it.
